Thanks for trying to help! I'm afraid my memory is a little foggy on the details but here's what I think it was like:
They weren't compacts. They were built like houses. I'm not sure if the roof opened but I think the front closed up so that all of the tiny pieces that came with it could be safely stored inside. I think there was some sort of track system underneat that allowed the sides of the buildings to slide in and out to make more rooms. I don't remember there being too many stickers if any. I think it was mostly just molded plastic and not in many colors - so it was unfortunately probably a cheaper off brand toy which is making it much harder to find.
I think the dress shop might have had two floors. But these playsets were very small - I'm think maybe 6-8 inches high. The barn was more like a stable probably. I can't remember much - but probably came with a horse and I think some fence pieces. The tiny plastic dolls had arms that came out from the sides (not just molded to the sides but there was space between the body and the arm) - but I don't think the arms moved. And I'm pretty sure they had separate legs too with space between them but they just bent at the waist - the legs didn't move independently. I'm almost positive they all had plastic ponytails in different colors (brown, black, blonde). I wish I could find just one little piece from the playsets to help solve it - but I have yet to come across anything.
